rMPRovEMENTiN celex-MACHINES.

The schedina referred to in time Leners Parent ana making pare of themme.

To all whom it may concern:

Be it known that I, JOHN R'. WILLIAMS, of Taunton, in the county ofBristol and. State of Massachusetts, have invented a new and improvedBrick-Press; and I do hereby declare that the following is a full,clear, andfexact description thereof, which will enable others 'skilledin the art to make and use the same,V reference being had to theaccompanying drawing forming part of this specification, in which-Figure l represents a plan or top view of my improved machine forpressing brick.

Figure 2 is a side elevation of the same.

' Figure 3 is a vertical longitudinalsection of the same, taken on theplane of the linea: fr, fig. 1.

Figure 4 isa vertical transverse section of the same, taken on the planeof the line y y, fig. 1.

Figure 5 is a detail vertical section on an enlarged scale of the pressand plunger.

Similar letters of reference indicate corresponding parts.

My invention relates to brick-presses, and consists in certain featuresof improvement, which will first be described in connection with allthat is necessary to a full understanding thereof', and then clearlyspecified in the summary or claim.

Ain the drawing represents the flame of my improved pressing-machine.The frame is made of wood or other suitable material, and of such sizeand shape as to be best adapted for the support of the machineryconnected with my press.

The sides ofthe frame are. straight or nearly so, to benear to thestraight edges of the endless belts B and C that are fitted over drumsnear the' two sides.

1n the frame A are'the bearings of two horizontal transverse shafts, I)E, one being near cach end of the frame.

The ends of these shafts carry drums a a, which serve to hold the broadbelts B C, as shown.

The shaft E carries one or more ratchet-wheels, b, so that it willreceive intermittent rotary motion from a pawl or pawls, e, pivoted toswinging levers d.

In the middle of the frame A is hung the horizontal transversedriving-shaft F, which receives rotary motion from suitable machinery totransmit the same tothe pressing and feeding apparatus.

Whenever the cam It strikes and depresses the levers H it will therebyextend the toggle-levers and move the sideI pieces together.

apart by the springs h.

I is the vertically-adjustable plunger of the press.

Its shank lis toothed and meshessinto the teeth of a pinion, nawhichreceives rotary motion from a toothed wheel, n.

I The wheel n is mounted upon a shaft, o, which carries also a pinion,p, shown in lig. 1,-and bydotted` lines in figs. 2 and 3.

The pinion p receives rotary motion from a toothed wheel, r, on a shaft,J.

rlhe shaft J serves as a pivot of a swinging frame,

L, which frame embraces the sides of the fram'eA,v

of the driving-shaft F,.will release the plate M and y frame L fromthe'catch.

Another cam, V, on the shaft F, serves to swing the frame L,on its pivotJ, into the both aforesaid positions.

rlhe cams vzt and c may he double on the shaft F, that is to say, one oneach side of the frame A, asindicated in iig. 4.

The plate M, when it swings away from the press, strikes the lever orlevers d, and imparts thereby intermittent rotary motion to the shafts DE and, belts B C The swinging motion of the frame L serves, by thegear-wheels nan, 1r, and r, to impart vertical reciprocation to theplunger I, in suoli manner that the said plunger is moved down wheneverthe plate M is carried over the press, and upA when said plate iscarried away from the press.

The plunger proper is made of two plates, w and o5, between which anoil-chamber, y, is formed.

Between the ,plates w x is` clamped a sheet, s, of paper or othcrfabrie,that projects slightly beyond the edges of the plunger, as indicated iniig. 5. The fabric will be soaked with the oil from the chambery, andwill, during the vertical adjustment of the plunger, wipe and smoothenthc sides and ends of the press. rlhis lubricating quality of the'plunger is of great importance, not only for facilitating the movementsof the' same, but also for preventing the clay from adhering to thesides of the press.

As soon as the cam le leaves the levers H the sides e will again bemoved' This By means of a belt, a', or otherwise, the shaft F impartsrotary motion to a vertical arbor, b', hung in the frame A.

'lhe arbor b carries a. toothed segment, e', which, meshing into apinion, d', serves to partly move the same.

The pinion d' is mounted upon thc lower part of a vertical shaft, N. Theupper part of this vshaft carries a toothed wheel, c', which meshes intothe teeth of a sliding rack, f.

The rack j" is arranged to slide in a horizontal grooved frame, 0, whichis supported transversely above the trame A aml press, extending overthe belt B, as shown.

The rack f carries a vertically-mijustable frame, I, which is providedwith or suspended from slotted arms g', and by which it is madevertically adjustable.

A spring, h', acting on the shaft N, serves to turn the saine so thatthe wheel e will throw the rack f and frame l over the bclt'B, asin iig..1.

turns the shaft N so as to carry the frame 1 toward the belt (l, intothe position indicated by dotted lines in tig. l. In this latterposit-ion the shaft N and frame l will be automatically locked by meansof a pin, i', which projects from the shaft N, and catches behind aspring catch,j', on the fra-me (l.

The plate M, when swung forward over the press, strikes the catch i',and releases the pin i', so that the spring 7i. may carry the shaft Xaround to move theframe l back over the bell l5.

\Vhenever the plate M swings forward over the press it swings up twobars or levers, R,whieh are pivoted to the sides of the frame A. lhescbars or levers ll, when swung up, elevate the-flame P, preparatory tothe release. of the pin i from the spring catch j". j The frame l hastwo proiecting' ears or ribs, l and an', of which one serves to feed thebrick to the press, while the other moves them away to the belt C.

The operation of the machine is as follows: The brick to be pressed areplaced in a single row upon a board, S, that is placed upon the apron B.A similar board, '.l, is placed upon the apron C. The rib Z' of thelia-me l will, when the shaft N is turned by the segment c', carry the'first brick from the boa-rd S upon the plunger of the press, which isthen tlush with J(he top of thesides and ends. \Vhen the brick has beenfairly carried'upon the plunger the frame L swligs forward to carry theplate M over the press an. to elevate, ny means of't-he bars R, theframe l. At the same time the plunger is moveddown sufficiently toadmit, the brick within the press, and the sides of the latter arecontracted to fairly compress the brick. When the brick has been pressedthe liu-une- L swings open again, the frame l is, by the spring h',moved over the board R, and the plunger to remove the `one previouslymade from the plunger to the board T.

The rspring catch j serves to lock the frame P after the salme hasbroughta new brick to the' press, and prevents thereby the rib m fromthrowing such brick back again.

When the board S has thus been emptied the board T will be full, andboth are removed to make room for others,vwith which the operation canagain be started.

By this means very rapid and entirely reliable op- 1- -Gl'ltoucan beobtained. The segment c', when it meshes into the pinion I,'

.Having thus described my invention,
